main[base-imageio] failing due to Pillow

[SeanLeRoy]

(Update Update) Seems the issue was resolved, should try again

(Update) They fixed the original issue in 2.28.1 but a new issue where another keyword was deprecated (fps) is now blocking us :( This issue describes it imageio/imageio#992

With the release of imageio 2.28.0 on 04/23/2023, main[base-imageio] failed when using imageio's pillow plugin to access images. As a result of this we have pinned 2.27.0 until this issue is resolved.

The main issue seems to come from trying to access the n_frames attribute.
